Sensei’s Divining Top’s second ability may be activated in response to its first ability. If so, you’ll draw a card, put Sensei’s Divining Top on top of your library, and then look at the top three cards and rearrange them.

If Sensei’s Divining Top leaves the battlefield while its second ability is on the stack, you’ll draw a card and leave Sensei’s Divining Top in the zone it’s moved to.
